When you say, OP, that banal diet talk is "something women can bond over", that makes me fucking livid.
I don't want people assuming that, because I have a uterus, I want to talk about calories and the size of my waist.
Talk to me about politics, news stories, the weather, music, cinema, tv. Want to keep it low-brow and uncontroversial? Fine. I'll hold my own on a waffle about Orange Is The New Black. Or the Brit Awards. Or the relative merits of various local pubs.
But to assume that I want to talk about Weightwatchers - and also sparing the men from that at the same time - is really quite offensive. There is more to me than my dress size. And I am more interested in what's in other people's heads than the labels on the clothes they wear.
I would hate to work in your office, OP. I would not fit in as one of the "office girls" who bangs on about calories and then eats cake when it's brought in for a birthday. Probably with a giggled "I shouldn't!" to add to the annoyance factor.
IME those who talk about diets never lose weight anyway. They're the ones loudly putting their Muller Lights in the office fridge and making a fuss about the fact that they're going to the gym after work. Then it's all over in a month.
Whereas (caveat - this is based on my own office environment!) those of us who don't "diet" and just eat well and exercise, tend to be slim - and don't bang on about what we eat.
We might talk about a run or a bike ride we've done, but it'll never be in an "oh, I burned 300 calories" way. It'll be to share a new route or comment on the scenery.
I hate it when people comment on my size and say to me "ooh you've lost the baby weight". Not least because I haven't, and they're not telling the truth - they're just saying something they think society expects them to - but because I'd rather they could come up with more relevant and interesting things to say to me.
